Conclusion
Bipolar steroid-eluting epicardial leads showed an acceptable long-term function, significantly better than unipolar non-steroid-eluting ones; therefore, they are more appropriate option in either adults or children with an indication for epicardial lead implantation. Furthermore, improved long-term function of epicardial leads, which is observed in bipolar steroid-eluting ones, indicated that they might be a better alternative for endocardial pacemakers in situations that epicardial leads are preferable.
